The outdoor unit is usually located in the rear or side of your house and it is where the heat from inside your home is dispersed. It contains the compressor, condenser coil, and a fan. The heat absorbed from your home's air is transferred to the refrigerant and then pumped to the outdoor unit.
It is a necessary evil to replace both, here’s why:
Matched systems perform better.
When outdoor ac units and heat pumps and air conditioning units are designed, they are built to work with a matched indoor unit. This matched system works in tandem to generate optimum efficiency and ideal system performance.Replacing an outdoor air conditioner unit without installing the matching indoor unit will work. However, you are jeopardizing the dependability of both the units and compromising your HVAC system’s efficiency, which may cost more in the long run.
Efficiency ratings are based on matched systems.
When you purchase a new HVAC unit, the heating and cooling efficiency ratings are based on matched system performance. That means if you bought a heat pump with an 18 SEER rating to help you save money on monthly bills, you won’t realize the full potential of those savings without the matching air handler.
Technology has changed.
Over the last 20 years, advances in residential HVAC technology have made outdoor and indoor HVAC units better than ever.When it comes to debris filtering, noise levels, and air handling performance, the units today simply outperform those installed in the past. Replacing both your indoor and outdoor units at the same time ensures that your HVAC system is running on the latest technology to make your home comfortable and your family healthy.
Replacing both now will save you money long-term
Like I mentioned above, a mixed system will result in poor efficiency, which will cost money on energy bills. But that isn’t the only money replacing just an outdoor unit will cost you.
Since most systems are installed as pairs, your indoor unit is probably just as old as your outdoor unit. Additionally, if your heat pump or air conditioner is 10 years old, it’s time to replace it anyway.
If you choose to replace only the outdoor ac unit, you’ll probably have to spend the money to replace the indoor unit shortly thereafter, and that means paying installation costs twice. Replacing both ensures you will have an efficient, dependable system for a longer period of time.
